With American botanist cypress apply reach Halier, the really beautiful doctrine that British botanist breaths out Qin Song to be a delegate thinks the flower of angiosperm is come by evolution of ball of leaf of primitive gymnospermous bisexual spore, consequently tentative idea angiosperm is the Benneisu that in coming from gymnosperm, eradicates already iron eye, draft Su Tie especially , the bud on ball of its spore leaf piece evolve for perianth, sporule leaf evolves for stamen, big spore leaf evolves for pistil , axis of ball of its spore leaf shortens for rachis.

以美国植物学家柏施及哈利尔，英国植物学家哈钦松为代表的真花学说认为被子植物的花是由原始裸子植物两性孢子叶球演化而来，因而设想被子植物是来自裸子植物中早已灭绝的本内苏铁目，非凡是拟苏铁，其孢子叶球上的苞片演变为花被，小孢子叶演变为雄蕊，大孢子叶演变为雌蕊，其孢子叶球轴则缩短为花轴。

Such as the ferns in the Stone Song Ya Ya doors and wedge the door leaf plants, they are The spore body was producing strobilus.

如蕨类植物中的石松亚门和楔叶亚门的植物，它们的孢子体均产生孢子叶球。

In the Taxus cuspidata nature reserve of Muling County in southeastern Heilongjiang Province, we selected 29 males and 30 females from a population of 271 natural T. cuspidata trees found by a route-checking survey to investigate the population fecundity. The strobilus development and the fruiting status, and their relationships with various ecological factors were examined by using the method of standard branches.

在黑龙江省穆棱东北红豆杉自然保护区，路线踏查到271株天然东北红豆杉，选择其中具有生殖活力的29雄株和30雌株作为样株，采用标准枝法对孢子叶球和结实状况及其与生态因子关系进行研究。

The results showed that the sex ratio of trees was 1 m 2 f, and the natural T. cuspidata tree was able to sexually reproduce for many years. Male trees had fecundity when the diameter at breast height ranged from 1.5 cm to 92 cm, while female trees had fecundity when the DBH from 9.5 cm to 68.1 cm. Male trees typically flowered at the age about 20 years earlier than female trees. The numbers of microstrobili were 3 times more than that of megastrobili, and only 1/10 megastrobili developed into seed. The numbers of strobili and seed were correlated with DBH, crown diameter and height of trees; however, no significant correlations were observed with other site factors. Numbers of strobili decreased from the upper to lower canopy layers, while the quantity of seed decreased from the middle, upper to lower canopy layers. Seed-setting rate increased from the upper to lower canopy layers. Numbers of strobili and seeds in different directions of the canopy were not uniform, but the differences weren't significant.

结果表明：现实东北红豆杉天然种群中，♀♂性比为1：2；天然东北红豆杉有性生殖持续时间长，雄株胸径在1.5~92cm，雌株胸径在9.5~68.1cm保持生殖状态，雄株较雌株早约20年进入花期；天然东北红豆杉小孢子叶球数量平均为大孢子叶球数量的3倍，大孢子叶球转化为果实的数量不足1/10，孢子叶球数量、结实数量与样株的胸径、冠幅、树高显著相关，与其他立地因子相关不显著；孢子叶球数量在冠层间的分布呈现由上至下的递减规律，而结实数量在冠层间沿中、上、下递减，结实率沿冠层自上而下递增；孢子叶球与结实数量在树冠不同朝向上也呈现出一定的特点，但总体上差异不显著。
